The two heartthrobs teamed up to sing Everybody's Got Somebody But Me, but they had a little surprise up their sleeve as they also presented the Best New Artist award to a totally deserving Kacey Musgraves!

How perfect!!!

We reckon you should ch-ch-check out their video (above)! Ha! We said "reckon"!

Zayn previewed the duet by posting a black and white pic of himself with Swifty on his Instagram -- but hey, she is bestiez with his girlfriend Gigi Hadid, so it wouldn't be unusual that they hang out... But collab?!
